Tomtom Navcore 9.510 One, One XL + Maps uk & Ireland 910.4952

Here are the tomtom navcore 9.510 that works on tomtom one and one xl, i used it on a tomtom one that hadn't been updated since 2006 and it works great.The only thing that i have noticed that doesn't work is the bluetooth on the tomtom one, i am unable to test on any other tomtom but as far as i know it works ok
